ASP.NET GridView 需要两个不同的操作按钮

Question

我有一个 GridView，我希望它有两个具有两个不同操作的按钮。我曾尝试制作它们两个 select 按钮，这将是最佳选择，但我无法让 ASP.NET 告诉我这两个按钮中的哪一个触发了事件。它会告诉您行索引，但不会告诉您我所看到的列。

我将其中一个按钮更改为编辑按钮，以便它调用不同的方法，然后将行置于编辑模式。我看不到取消编辑的方法，而且它误用了代码的预期用途。

按钮位于 gv 的第一列和最后一列。

<asp:GridView ID="gvMedList" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataSourceID="dsMedList" GridLines="Vertical" OnSelectedIndexChanged="gvMedAction" OnDataBound="gvMedList_DataBound" OnRowEditing="gvRefillButton">
    <AlternatingRowStyle BackColor="#DCDCDC" />
    <Columns>
        <asp:CommandField ButtonType="Button" SelectText=" -STOP- " ShowSelectButton="True" ShowCancelButton="False" />
        <asp:CheckBoxField DataField="Active_Med" HeaderText="Active" SortExpression="Active_Med" >
        <HeaderStyle Width="50px" />

        </asp:BoundField>
        <asp:BoundField DataField="Dispense_Unit" HeaderText="Unit" SortExpression="Dispense_Unit" ShowHeader="False" >
        <ItemStyle Width="50px" />

使用命令名属性

前端

<asp:GridView ID="gvMedList" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataSourceID="dsMedList" GridLines="Vertical" OnSelectedIndexChanged="gvMedAction" OnDataBound="gvMedList_DataBound" OnRowEditing="gvRefillButton" OnRowCommand="gvMedList_RowCommand">

        <Columns>
            <asp:TemplateField HeaderText="ColumnName">
                <ItemTemplate>
                    <asp:Button ID="btnDoSomething" runat="server" CommandName="DoSomething" Text="Do Something" />
                </ItemTemplate>
            </asp:TemplateField>

            <asp:TemplateField HeaderText="AnotherColumn">
                <ItemTemplate>
                    <asp:ImageButton ID="btnImageSomething" runat="server" CommandName="DoSomethingElse" ImageUrl="~/images/yes.png" />
                </ItemTemplate>
            </asp:TemplateField>

        </Columns>

    </asp:GridView>

代码隐藏（假定为 C#...如果您需要 VB 让我知道）

protected void gvMedList_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "DoSomething")
        {
            // code to execute
        }

        if (e.CommandName == "DoSomethingElse")
        {
            // code to execute
        }
    }
